Wacker Neuson 5200012216 Air Filter Secondary G70/100/120T4I

The Wacker Neuson Air Filter Secondary G70/100/120T4I is a genuine OEM secondary air filter designed for the G70, G100, G120, G130, and G150 portable generator series. As a factory-sourced component, it meets the exact specifications Wacker Neuson engineers built into these Tier 4i and Tier 4F compliant generators — so you know the fit and filtration performance are right the first time. This secondary filter works in tandem with the primary air filter to catch any fine particles that pass through the first stage, protecting the engine from abrasive contamination. Confirm your generator's model number against the fitment list to ensure this is the correct filter for your configuration, including Standard, Cold Weather, Custom, Extended Run, and Hertz variants.

Key Features

• Genuine OEM Filtration Media — Manufactured to Wacker Neuson's exact filtration specification, ensuring the secondary stage captures fine particulates that a primary filter alone may pass, maintaining clean airflow to the engine.
• Drop-In Replacement — Engineered to seat correctly in the OEM air cleaner housing on G-series generators, with no trimming or adapter hardware needed for installation.
• Broad G-Series Compatibility — Fits a wide range of G70, G100, G120, G130, and G150 generator configurations including Standard, Cold Weather, Custom, Extended Run, Hertz, and URI HVAC variants across Tier 4i and Tier 4F emissions platforms.
• Engine Protection Between Service Intervals — A functioning secondary filter prevents fine dust and debris from reaching the intake, preserving cylinder bore and piston ring condition over the long run. A clogged or missing secondary element forces the engine to run lean and accelerates internal wear.
• Emissions System Compliance — Using the correct OEM air filtration components on Tier 4i and Tier 4F engines supports proper combustion efficiency and helps keep the engine within its certified emissions operating range.

The secondary air filter is the second line of defense in a two-stage air filtration system. While the primary filter removes the bulk of dust and debris drawn in through the air intake, the secondary element captures the finer particles that make it past the first stage — particles small enough to cause abrasive wear on cylinder walls, piston rings, and valve seats. On portable generator engines running in dusty or demanding jobsite environments, a clean and intact secondary filter is critical to maintaining engine compression and extending service life. When the secondary element becomes clogged or deteriorates, airflow restriction increases, fuel-to-air ratios shift, and the engine can run hot, produce less power, and wear prematurely.
